Hyperbolas: Question Attached :)
the key is to find the asymptotes for the graph as tho it was centered at the origin; then apply the shifts expressed in the equation for the values of x and y
How do I do that?
first, notice which way the hyper is positioned; the positive side tells you which way the vertexes lie .... Which value is the positive on this one; x or y?
The x.
good, the hyper splits open left and right then. the denoms tell us important values for our asymps; the sqrt(25) and the sqrt(9) form the legs of a right triangle
but more importantly, they tell us the "slope" of the line that our asymptotes will take, namely; sqrt(y denom)/sqrt(x denom) if i recall it correctly
in this case, we have what: sqrt(9) ------- = the base of the answer, then we have to shift it sqrt(25)
can you see what the answer will be from that?
The fourth?
i would go with the 4th option :)
thank you for helping :)
youre welcome :)
